How does one make the "highlight" for the infoWindow a different shape

[MatthewDewell]

I'm making an infoWindow for a circle/point on my map in a graphics layer.  The point plots fine, and when I click on the point it brings up the infoWindow/InfoTemplate fine.  The one problem I am having is that there is a box drawn around my point that is very large, the "highlight", and it is much larger than the point.   I would actually like it to be a circle for the shape of the "highlight" an have it be closer to the point that was clicked on.  Does anyone have any idea, how to change the shape, and how to bring the size down?

Thank You

Never mind.  I figured it out.  I did the following:

var infoWindowSymbol = new esri.symbol.SimpleMarkerSymbol();

infoWindowSymbol.setStyle(esri.symbol.SimpleMarkerSymbol.STYLE_CIRCLE);

infoWindowSymbol.setSize(30);

infoWindowSymbol.setColor(new Color([255,255,0,0.2]));

this.map.infoWindow.markerSymbol = infoWindowSymbol;
